Because the FB25 boxer engine positions the spark plugs horizontally against the frame rails, they endure significant radiant heat cycling. Over time, the factory coil packs experience internal winding resistance variations, leading to weak spark energy, erratic idling, partial throttle hesitation, and eventual P0300-series misfire codes. Simultaneously, standard plug electrodes erode, increasing the spark gap, which demands higher firing voltages and prematurely stresses the factory coil packs to the point of failure.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eThis comprehensive ignition service kit bundles high-output ignition coils with premium iridium-tipped spark plugs to re-establish peak firing efficiency. The upgraded coils feature enhanced copper windings shielded by high-temperature epoxy, preventing voltage leaks and ensuring a consistent spark output even under heavy thermal loads. Paired with the ultra-fine wire iridium center electrodes, these plugs require lower firing voltage while delivering a more concentrated spark kernel. This combination significantly optimizes fuel burn within the cylinder, rectifying hesitation, restoring factory fuel economy, and ensuring reliable cold starts. The iridium construction also provides superior resistance to electrode wear, extending service intervals well beyond OEM copper or platinum variants.\u003c\/p\u003e\n  \n  \u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e2014-2016 Subaru Forester\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eFB25 \/ SJ\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e170 hp \/ 174 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n \n  \u003ch3\u003eCompatibility\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e2014 Subaru Forester 2.5L H4\u003c\/li\u003e\n    \u003cli\u003e2015 Subaru Forester 2.5L H4\u003c\/li\u003e\n    \u003cli\u003e2016 Subaru Forester 2.5L H4\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe Subaru Standard\u003c\/h3\u003e\n  \u003cp\u003eWhether navigating technical off-road trails or managing daily commutes, a robust ignition system is critical for the symmetrical AWD powertrain.
